Application filed March is, 1921.

To all to 710m it may concern:

Be it known that we, LoREN L. WHITNEY and TVILLIAM C. HnDGoocK, citizensof the United States, residing, respectively, at Hammond, in the countyof Lake and State of Indiana, and at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inBrake-Beam Fulcrums, of which the following is a specification.

This invention relates to brake beam fulcrums.

One object of the invention is to provide a simple and eflicient forgedbrake beam fulcrum in which the body portion enclosing the lever issecurely connected by an integral bridge and at the same time permits ofthe application of a separable suspension attachment and of a separabletension rod seat which can be easily made in a separate piece and whichis not required to be rightor left-hand for rightand left-hand fulcrums,the same seat being applicable to either rightor left-hand fulcrums.

Another object is to provide a simple and improved forged brake beamfulcrum adapted to meet the various requirements for successfulcommercial use.

These and other objects are accomplished by means of the arrangementdisclosed on the accompanying sheet of drawings, in which Figure 1 is atop plan View of a forged fulcrum embodying our invention;

Figure 2 is a side elevation of same; and,

Figure 3 is an end view of the same fulcrum.

The various novel features of our invention will be apparent from thefollowing description and drawings and will be particularly pointed outin the appended claims.

Referring to the figures of the drawings, it will be noted that the bodyportion of the fulcrum includes two parallel arms 10 and 11 connected attheir front ends by an integrally formed bridge 12. These spaced arms 10and 11 are provided with aligned perforations 13 and 14 for thereception oi a pivot pin to which is connected the usual brake lever,not shown, but which is located between said arms. The arms 10 and 11terminate rearwardly in two offset ortions 15 and $16, which may besecured to Serial No. 453,326.

the compression member of a brake beam in an; suitable manner.

The seat member 17 is formed of a sepa rate iece and is provided with aseat 18 for the reception of the tension rod of the brake beam.Extending rearwardly from the body of the seat member 1'? is a shank 19which extends through an opening 20 in the bridge 12 of the main bodyportion and which is riveted to form a head 21 for securing the tensionrod seat member to the main body of the fulcrum. By forming the tensionrod seat in a member separate from the main body of the fulcrum, thenecessity of mating rightand left-hand seats is obviated, for it isapparent that these seat members may be applied to fulcrums arranged forrightand left-hand use. This greatly simplifies and reduces the numberof dies required for producing the fulcrum seat.

A suspension attachment is provided for this fulcrum and it is in theform of a separate piece 22 shaped to provide a suitable receivingportion 23 for a suspension hanger and provided with a hole 24 throughwhich the shank 19 of the tension rod seat extends for securely holdingthe suspension attachment 22 in position between. the bridge 12 of themain portion of the fulcrum and tDG seat member 1'? thereof. It will beun- -rstood that when the shank 19 is passed trough the openings 2": and20, the shank s in a heated condition and the other parts *elativelycool, whereupon the parts in question are riveted together.

It is our intention to cover all modifications of the invention fallingwithin the spirit and scope of the following claims.

We claim:

(ill

1.. A forged. fulcrum comprising a plurality of separate'membersincluding a lever receivingmember, a tension rod receiving member, and asuspension attachment memher, one of said members having a shank bymeans of which. all of said members are connected together,

2. A forged fulcrum comprising a plurality of separate members includinga lever receiving member, a tension rod re-- ceiving member, and asuspension attachment member, said tension rod receiving member having ashank passing through openings in said lever receiving member and saidsuspension attachment member whereby all of said members are fixedlyconnected together.

3. A forged fulcrum comprising three separate members including a leverreceiving member a tension rod receiving member, and a suspensionattachment member,

the latter being secured between said other two members. 10
